ROBERT A. GILLESPIE, OF PITTSBURGH, PENNSYLVANIA.

HOUSEHOLD SLICER AND GRATER.

T 0 all whom it may concern Be it known that I, ROBERT A. Grnrnsrna, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Household Slicers and Graters, of which the following is a specification.

The primary object of this invention is to provide a simple, durable and easily operated household device for slicing, grating and coring fruits, vegetables, etc., and one which may be readily taken apart and assembled.

The invention includes a series of interchangeable rotary cutting members and means for mounting them upon an operatin shaft, as well as a shield for the cutters and a removable supporting shelf upon which the articles rest while being acted upon by .the cutters, all of a new and improved construction.

It is characteristic of my device that all of its parts are of an exceedingly simple and durable construction readily taken apart and assembled, and further the cutting members may be interchanged without removing the shield or supporting shelf, and the latter may be removed and replaced without disturbing the cutting members.

The invention consists in certain novel features of construction, and in the assemblage and combination of parts hereinafter fully described and claimed and illustrated in preferred form in the accompanying drawings, wherein Figure 1 is a front elevation of the device embodying my improvements. Fig. 2 a side elevation of the same, with the cutting member and supporting shelf in section. Fig. 3

Fig. f a sectional detail on line 4"4: of Fig. 2, illustrating the connection between the supporting bracket and shelf. Fig. 5 a similar view on an enlarged scale on line of Fig. 1, showing the coring member attached to the cutting disk.

Referring to the drawings, 2 is the supporting bracket which may be of any preferred construction, such for instance as that shown, comprising a clamping member 3 provided with two upright supporting members a connected by a cross bar and hav ing their upper ends adapted to form bearings 5, in which operating shaft 6 is journaled. To one end of shaft 6 an operating crank handle 7 may be secured by a cotter Specification of Letters Patent.

Application filed September 12, 1910. Serial No. 581,723.

pin 8, and to its opposite end a cutter carrying member, comprising a collar 9 provided with a bayonet joint 10 for securing it thereon, and outwardly extending arms 11 having their outer ends connected to a cutter supporting ring 12. Ring 12 is provided. on its outer face with an annular shouldered recess 13, in which cutting disk 1% fits and is held by a retaining ring 15 clamped in position by bolts 16 passing through the rings and outer edge of disk and provided with half round heads 17, adapted when in the position shown in Fig. 5 to hold the rings and disk firmly together and when in the reverse position permit of the ready removal of the retaining ring and disk from the supporting ring.

The article to be acted upon by the cutting disk is supported upon a transversely disposed shelf 18 provided with a rectangular frame-like extension 19 surrounding the cutter below its center, and provided upon its rear edge with a depending member 20 having in one face a vertically disposed groove or recess 21 with dove tail edges and of a less width at the top than the bottom, said groove being adapted to engage and interlock with a correspondingly shaped support 22 formed upon the adjacent upright 4 of bracket 2.

By reference to Figs. 3 and i, it will be seen that a very slight upward movement will suffice to disengage members 20 and 22 when the shelf can be readily slipped from around the cutting disk without disturbing the latter, while a reversal of the operation will secure it firmly in operative position. A resilient shield 23 extends above and around the cutting disk and is provided near each end with grooves 2% adapted to engage the end members of shelf extension 19, when it is sprung into position and hold it firmly in place, as shown in Fig. 1.

While any desired form of cutting disk may be used in connecton with my device a very simple and convenient form and one well adapted to the purpose is that shown in Figs. 1, 2, 3 and 5, comprising a sheet metal body provided upon its cutting face with an annular depression 25 approximately Vshaped in cross-section, the outer surfaces of which are somewhat longer than the inner and provided with a series of radial slots 26 of sufficient length to permit the metal on one side to be struck up to form cutting edges 27, which will successivel engage an article supported upon shelf 18 when the disk is rotated in the di rection indicated by arrow a of Fig. 1.

By reference to Fig, 3 it will be seen that a cutting disk constructed in accordance with the above will be braced in such a manner as to render it exceedingly rigid, and that when the article resting upon shelf 18 is in position to be engaged by edges 27 it will project into annular depression 25, in such a manner that it will be held firmly and prevented from slipping upon the shelf while being sliced. The disk may also be provided with a centrally located socket 28 secured to its rear face and adapted to receive a coring member 29 held therein, centrally in line with shaft 6 by means of a slot and pin' connection 30, as shown in Fig. 5.

I claim:

1. The combination of a bracket, a cutter rotatable thereon about a horizontal axis, and a shelf formed with an opening adapted to embrace the cutter, the shelf and bracket formed with cooperating parts adapted to interlock for supporting the shelf.

2. The combination of a bracket, a horizontal shaft journaled in the bracket with its ends projecting from opposite sides thereof and with a crank at one of said ends, a cutter secured to the other end of the shaft, a shelf formed with a vertical opening for surrounding the cutter with the portion of the shelf at the outer side of the cutter adapted to support the material being cut, the part of the shelf adjacent the inner side of the cutter and the bracket formed with cooperating parts adapted to interlock for supporting the shelf.

3. The combination of a bracket, a cutter rotatable thereon about a horizontal axis, a shelf formed with an opening adapted to embrace the cutter, a vertical upwardly tapering boss on one face of the bracket, and the shelf formed with a vertical upwardly tapering socket adapted to move downwardly into engagement with the boss when the shelf is in cutter-surrounding position.

i. A. household slicer and grater comprising a supporting bracket, a rotatable shaft mounted thereon provided with a cutter, a transversely disposed shelf removaloly mounted upon the supporting bracket in position to cooperate with the cutter and provided with an opening adapted to receive a shield, a cutter shield adapted to be of the extension frame at opposite ends when sprung into position.

6. A household slicer and grater comprising a supporting bracket, a rotatable shaft mounted thereon and provided at one end with means to receive a cutter, a transversely disposed shelf removably mounted upon the supporting bracket and provided with. an opening to receive a shield, together with a shield partially surrounding the shaft and adapted to engage opposite ends of the opening to hold the shield in position.

7. A cutter for household-slicers and graters comprising a sheet metal disk provided upon its cutting face with an annular depression approximately V-shaped in crosssection and having radial slots in one of its faces, the metal on one side of the slots being raised to form cutting edges.

8. A cutter for household slicers and graters comprising a sheet-metal disk provided upon its cutting face with an annular depression approximately V-shaped in cross-section, the outer surface thereof being of a different length than the inner, and provided with radial slots, the metal of one side of said slots being raised to form cutting edges.

9. The combination of a supporting bracket, a horizontal shaft journaled therein, the shaft provided with a crank, a cutter secured to the shaft and located at one side of the frame, a shelf supporting arm removably secured to the bracket, and a shelf sup ported by the arm in position in front of the cutter for sustaining the material being operated upon.

In testimony whereof T affix my signature in presence of two witnesses.
